Why does my plasma cutter sputter?

Why does my plasma cutter sputter?

One common plasma nozzle problem occurs when the orifice becomes blocked, sometimes due to molten material contacting the tip and then cooling down and hardening there, altering the plasma flow. An off-center stream will steadily wear down the orifice.

What air pressure is required for plasma cutting?

90-120 PSI

Why does my plasma cutter keep stopping?

The cutter nozzle has a second set of channels. These channels release a constant flow of shielding gas around the cutting area. The symptoms are often that the plasma cutter won’t initiate an arc on the metal, or the arc will start and stop erratically while you’re cutting.

Why does my plasma cutter cut on an angle?

(Excessive) Positive bevel This problem may be caused by a worn nozzle, high torch standoff (arc voltage), inadequate amperage, or excessive speed. Improper cut direction around the part may also cause excessive positive bevel angle.

Why do all plasma cuts have a slight bevel?

High definition plasma produces less bevel than a standard cutter. In the process to create a plasma arc for cutting the gas must be shaped into a vortex. Because of this an arc will have a direction of rotation. This will cause one side of the cut to have more bevel than the other.

How can I improve the quality of my plasma cut?

Improve cut quality on metal with these plasma cutting tips

  1. Positive cut angle. More material was removed from the top of the cut surface than from the bottom.
  2. Negative cut angle. More material was removed from the bottom of the cut surface than from the top.
  3. Top edge rounding.
  4. High-speed dross.
  5. Low-speed dross.
  6. Top spatter.

How long do consumables last in a plasma cutter?

2 to 4 days

Which plasma gas gives the best results for cutting mild steel?


What do you wear when using a plasma cutter?

Safety glasses with yellow lenses are recommended to block potentially damaging blue light, and a secondary shield between the operator and the cutting torch, perhaps a welding curtain or dark plastic shield, could shade the operator from the most damaging radiation.

Do you need eye protection when using a plasma cutter?

One of the many purposes of wearing safety glasses or goggles when plasma cutting is to protect your eyes from radiation and UV rays. Proper plasma safety requires protecting your eyes, face, and your exposed skin. You need to shield your eyes and face with proper plasma cutting glasses, goggles, and/or helmet.

Do you need to wear a mask when using a plasma cutter?

Do you need a welding mask for plasma cutting? Technically, no, you do not. Many people tend to wear goggles when it comes to plasma cutting or even safety glasses that darken. However, if the torch you are using has enough amps to it, then a welding mask would be ideal for safety reasons.

Do you need a compressor for a plasma cutter?

One of the most important requirements for a quality cut when using a plasma cutter is sufficient air pressure to blast the plasma out of the cut. That means you need a quality air compressor as well as a quality plasma cutter, both inside the same cabinet.

What is the best plasma cutter under $500?

Plasma Cutters Under $500 with Reviews

  6. Super Deal DC Inverter (CUT 50) Plasma Cutter.

How big of a compressor do I need for a plasma cutter?

The general rule for buying a compressor is the bigger the better. Manufactures recommend you buy a compressor that is rated for about 1.5 times the CFM (cubic feet per minute) of your plasma cutter. For example, the Hypertherm Powermax30 XP requires 4 CFM at 80 PSI.

What is needed for plasma cutting?

The main consumable parts required for plasma arc generation are the electrode, swirl ring, and nozzle. An additional shielding cap may be used to further improve cut quality, and all the parts are held together by inner and outer retaining caps.

Can a plasma cutter cut wood?

Any thickness from 30 gauge through 1 inch can be cut, depending on the plasma cutter used. Plastics and wood are not electrically conductive and cannot be plasma cut.

Can a MIG welder be used as a plasma cutter?

A MIG welder can be used as a plasma cutter. You’ll need an air compressor and carbon electrode in place of wire along with a number of small items.

How thick can plasma cutter cut?

about 1 inch

What is a disadvantage of plasma cutting?

While it limits ambient heat, plasma cutting is noisy and generates excess fumes. Make sure that all plasma cutting takes place in an open, ventilated workshop. Plasma is also infamous for creating very bright flashes while the cutting is ongoing.

Why are plasma cutters so expensive?

resulting in very nice cut quality at very high speeds, and with a very low operating cost (long consumable parts life). With the latest inverter based power supply technology…these systems can be small, reliable, and can cut with exceptional quality, ease and speed. There…..that’s why plasma can be expensive!

Can a plasma cutter cut glass?

Can plasma cutter cut glass? Much like wood, glass is not electrically conductive, and so it cannot be cut with a plasma cutter. He uses a thin sheet of metal in front of the glass to create an arc that can melt through the glass!

How thick of metal can a 50 amp plasma cutter cut?


Can you cut yourself with a plasma cutter?

The intensely hot and powerful plasma arc can quickly cut though gloves and skin. To prevent injury, do not grip material near the cutting path. The pilot arc can cause burns, too, so keep away from the torch tip when pressing the trigger.

Can a plasma cutter cut granite?

We can cut parts from metal, stone, foam, copper, brass, graphite composites, rubber, granite, plastic and even paper by using our water jet cutting equipment.

Is laser cutting cheaper than water jet?

Plasma operating cost would again be the lowest, and is typically estimated at approximately $15/hour. The cost of laser would be slightly higher, typically estimated at around $20/hour. Waterjet is usually considered to be the most expensive, typically estimated at about $30/hour.

What is the difference between laser cutting and plasma cutting?

Laser cutting is a precise thermal cutting process, utilizing a focused beam of light. Plasma cutting, on the other hand, uses a mixture of gases in order to form a cut. With our high definition plasma cutting equipment, we are able to perform bevel cuts on parts as required.

Can a plasma cut a diamond?

Diamond plate cuts well with Plasma. just diamonds down like explained above.

Will a plasma cutter cut hardened steel?

-Air plasma cutting will create a Nitride hardened edge on steel of bvetween . 006″ and . 010″ thickness. A few passes with a grinder can remove it before machining.

How accurate are plasma cutters?

A high-precision system can achieve a cut accuracy of ±0.01 to 0.05 in. and kerf widths as narrow as 0.05 in. Consumables can last from 1,300 to more than 3,700 arc starts, and systems can cut any conductive material from 10 gauge up to 2 in.
